Extraordinary energy-saving performance
Designed for Actual Operation Performance. Panasonic
builds air conditioning systems not only with a high EER
for rated operation, but also with Seasonal-EER
appropriate to the customer’s actual environment of use.
For instance, with rated operation, outdoor temperature is
constant at 35 °C, but in reality the outdoor temperature is
continuously changing. Consequently, required air
conditioning performance also changes. That’s why
Panasonic implements the following kind of proprietary
control.
1 | Set temperature is rapidly attained; full-load operating
time is kept to a minimum.
2 | The frequency of forced oil recovery is minimised. The
volume of oil within the compressors is monitored
precisely by sensors, so forced oil recovery under fullload operation is conducted only when necessary. Since
this suppresses noise due to oil recovery, comfort is
maintained.
3 | Panasonic pursues a high EER, of course, as well as
high EER in part load, for energy saving performance
under a broad range of loads.
Compressor efficiency electric system VRF.
Panasonic’s design concept contributes to substantial
energy cost reductions.
